I paid him around £100 for the software so about 25% the cost of xHP. He basically just took the original BMW software from the E92 M3 GTS and adjusted it to work with the lower N54 RPM limit, final drive and different shifter.

It's a really popular conversion for E9x M3s.
Richard, is it easy to download into a Z4 ?

It took about 20min with a laptop. The guy that did it for me goes by the name of Olza on the forums. It was just the same as updating a module with Winkfp.

Hi, Richard. As always, you’ve been very generous with me from the get-go. Thank you.

Rewinding to your xHP vs GTS comparison. You’ve ginned up a xHP map for me in November 2021. Will GTS be a massive leap from the xHP version you shared ? Where exactly will I feel improvements ? Does anything change in Comfort ?

I couldn’t find an Olza here. Could you please connect us ?

Did Olza download the map in person or remote ?

If I need to remove GTS for the California emission test, would it be easy to revert to factory map ?

Thanks again.

I'd like to get the GTS map as well. Tried reaching out to Olza on Spoolstreet, but not getting a response.
